THOMAS SPENCER MILLER, OIE SOUTH ORANGE, NEW' JERSEY.

MARINE TRANSFER.

Specification of Letters Patent.

` 'Application filed March 5, 190e. serial No. 481,450.

To all whom it may concern: n

Be it known that I, THOMAS xSPENCER MILLER, a citizen of the United States, and a resident of South Orange, county of Essex, and State of New Jersey, have invented a new and useful Improvement in Marine Transfers, of which the following is a specication.

In my application No; 186552 filed December 26, 1903, I haveshown a marine transfer containing many generic' features retained by my present construction.

In the accompanying drawings, Figure l is a cross section of a collier containing my present invention. Fig. 2 is a plan v`of a section thereof. Fig. 3 is a longitudinal section of either the'rope drum 16, or 4, which are of identical construction. Fig. 4L is an elevation of another form of rope drum engine which may be used at 4 or 17. Fig. 5 is a plan of the same. Fig. 6 is ay longitudinal section of the drumk thereof. Fig. 7 is a fragmentary view ofthe friction ring with the radial spaces. n

Either of the forms of rope drum engines and those portions of my invention contained therein may be used in other combinations than the marine transfer shown in .Figs 1 and 2.

A is the collier and B, a warship alongside taking coal therefrom; The hull of this collier will preferably be divided into compartments by water-tight partitionsas described in said application and will be provided vvith its own propelling apparatus.

H is the deck provided with the hatchways L, h2, h3, h4.

J J2 are a pair of masts located adjacent the corners of the hatchways 71,', 7b2 and J s, J 4 are another pair of masts located adjacent the corners of the hatchways k3, h4.

j,'j2 are booms extending from the mast J 2 to points above the centers ofthe hatchways 7L', 7b2 at an elevation above the ordinary boat equipment.

js, j* are corresponding booms extending from the mast J4 above the hatchways 71.3 and h4, respectively.

z", 2 are booms extending from the mast J outboard to points respectively opposite the centers of the hatchways L- and 7b2.

i3 and 4 are booms extendingfrom the mast J 3 outboard to points respectively opposite the centers of the hatchways 7b3', 7b4.

Since a duplicate apparatus coperates eratedjbyy the ropes 2, 3, actuated by thefrope,

with l'each hatchway, will suffice to de;V .scribe the apparatus coperating with the` drum engine 4E hereinafter more particularly described.

5 is a pulley block over which the ropes 2,

3, pass at the topof the boom 1j. `6 is ya,

guide-sheave for said ropes at the. opposite end of said boom.

The bucket operating ropes run to diffen.

entparts 16a and 16by of the drum 4, but are wound thereon in the same direction so that when the drum parts move together the'tvvo.

ropes are paid out or hauled in inunison.

`7 is a swinger frame containing the u sheaves 8, 9. and `10 between each two of which the ropes2 and 3, respectively, pass,l i

11 is an inhaul swinger rope fast@ at 1'2 toy the guide-sheave 15 fast to the'mast J f and thence to the "part `16a of the rope drum `,7'5` `to one vend of the swinger frame and eX-f 16 of the rope drum engine 17, to 'which drum part its end is made fast. outhaul-swinger rope fast at 19 to the 0pposite end of the swinger framev andeX- tending over a sheave 2O fast atl the outer- 'end ofthe boom c, thence diagonallyY over the sheave 21 at the opposite end of the boom z" to part 16" of ldrum'16 of the rope drumv engine 17, to which drum part its end ismade fast. The inhaul and outhaul ropes are kwound inversely on the drum parts 16, l

16) sol that as one is hauled in the'other` is` paid out in consonance therewith.v

The .runs `of the inhaul and outhaul swinger ropes 11 and 18 between the sheaves 13 and 20 carrythe swinger frame 7 from the position shown in dotted linesto the position shown in full linesv in Fig. 1, passing transversely over the center' of the hatchway and thence outboard to the outer end. of the mast c" above the hatchway 'of the warship. To better maintain the control of the swinger frame 7, Il provide a suspension rope 23 secured about the center of gravity of on a traveler 26 running on the inclined rope 27 stretched between the ship rail 14 and the end of the boom j. 28 is a stop on the rope 27 fixing the downward extremity of traveler movement. As-the swinger frame is hauled forward or backward by the outhaul or inhaul rope, this suspender rope and its counterweight will maintain a constant lift on the swinger frame whereby it will be caused to run straight and true with a minimum of vibration. Furthermore, the suspender rope, instead of being made fast to the counterweight 25, extends through and beyond it and is made fast to the supplemental counterweight 25a. Therefore, when the swinger frame reaches a point where the counterweight 25 rests on the stop 28 (which will be when the swinger frame is over the hatchway and when its uncounterbalanced weight is an advantage toward maintaining its normal position) the further descent of the supplemental counterweight 25a will take any slack out of the suspender rope.

I will next describe the rope drum engine shown at 4 and 17. These are alike and a description of one will answer for both. They are placed inversely as shown in Fig. 1, so that a single operator standing on the deck at 30, between them can at the same time reach and operate the controlling levers of both.

31 and 32 are the bearings in the frame for the shaft 33. The rope drum parts 16a and 16b are respectively loose upon the shaft and splined thereto.

34 is a cross key extending through a slot in the shaft bearing against a collar 35, which in turn bears against the end of the hub of the splined drum part 1Gb.

36 is a set screw threaded into the end of the shaft and thrusting against the cross key 34 through the pin 37.

38 is a lock nut.

39 is the spur wheel fast on the shaft, which meshes with a pinion on the engine crank-shaft.

By adjusting the set screw 36 the drum part 16b is forced toward the drum part 16 and this in turn is forced toward the spur wheel 39. To provide the friction surfaces which, under the adjusted thrust of the set screw 36, transmit the power from the spur wheel to the drum part 16a, and thence in turn to the drum part 16h, I make the following provision: Between the drum parts 16a and 16b is the friction ring 40 composed of an alloy of soft cast-iron and steel and also the friction ring 41 composed of cast steel. These rings are fast, respectively, to the drum parts 16a and 16h. Between the drum part 16a and the spur wheel 39 is the friction ring 42 of an alloy of soft castiron and steel and the friction ring 43 of cast steel, being fast, respectively, to the spur wheel and the drum part 16a. Behind the friction ring 43 the flange of the drum is provided with an annular air space 44 ventilated by a series of holes 45. The air entering the annular passage 44 through these holes comes directly in contact with the rear of the friction ring 43 opposite the friction surface and keeps it cool. A corresponding annular passage 46 and ventilating holes 47 are provided in the body of the drum part 16b at the back of the friction ring 41 for the cooling thereof. The friction rings 40 and 42 are both made in sections, as shown in detail in Fig. 7, the various sections being separated by radial spaces 4S connecting at both ends with the open air so as to provide a free circulation of air for cooling the sections. These friction rings are described and fully covered in my Patent No. 715111, Dec. 2, 1902. 49 is an ordinary band brake operating upon the flange of the drum part 16a and, if need be, there may be another band brake operating upon the fiange of the crank wheel 50.

The drum parts 16a and 16b and the friction rings 40 and 41 are preferably made of equal diameter, so that an undivided drum surface will be presented between the end ianges.

The engine 4 for controlling the bucket is operated as follows: The set screw 36 is so adjusted that the pressure between the friction surfaces is just sufficient to take up the slack in holding rope 2 wound on drum part 16a.; the two drum parts moving in unison with the spur wheel, excepting when an excessive rope pull occurs on drum part 16 and when the band brake 49 is applied, at which times the friction surfaces will slip. The engine is reversible. The operator controls the engine so as to pay out upon both ropes 2 and 3, with the brake 49 unset, until the bucket nearly reaches the coal or cargo. He then, through a foot lever, sets the brake 49 which will arrest the drum part 16 and the holding rope 2 secured thereto and cause the blades of the bucket to open. He then releases the brake and the further motion of the engine lowers the bucket onto the pile. He now reverses the engine which winds up closing rope 3 on drum part 16" and the motion of drum part 16b being arrested by excessive pull closes the bucket. Then the bucket is closed, drum part 16" will continue to wind up rope 3 and the up to the swinger frame the steam may be shut off and the brakey applied to the crank disk 50.y The operator can then, by the use of this brake, give suicient slack to enable the swinger frame to swingthe bucket to its outward position. l f

The swinger engine is operated` as'fellows: Assume that the outhaul swinger rope is fast to the drum part 16a and theinhaul swinger rope fast to the drum kpart 16". By reversing the engine the operator can swing the bucket in or out as though the inhaul and outhaul ropes were an endless rope connected with a single drum. I-Ie is enabled to keep them taut by the application of the brake 49 to cause a differential movementi between the drum parts 16a and 16b rand thus take up any slack that may occur. Set screw 36 on the swinger engineis'so adjusted that the pressure between the friction surfaces issuflicient to swing the loaded bucket to its extreme outboard positionj that is to say, it is considerably greater than the bucket engine. When the swinger vframe reaches the end of the swing in either direction the steam may be shut of and the frame held in that position by the application of the brake'49. It will thus be seen that (the brake on the crankshaft being unnecessary for regular use) I have provided a twopart drum upon a single shaft operated by' two levers (the steam lever and the brake lever) which will open, close; raise, lower and permit the swing of the bucket at/the will of the operator, and I haveialso provided a similar enginek by which the same operator, standing in the same position, can, at the same time control the swing; there being altogether only four levers essential for the attention of the operator and generally only three requiringhis attention, be-

cause on the swinger engine the brake lever would only be requiredv in thei'event Ithat the operator desired to take up theY slack or to shut off his steam at the endv of a swing. The engine shown in Figs. 4, v,5 and 6 presents a further very important invention, adding to the simplicity, economy and smallness of space required. In this construction there is a loose drum part 1621, the splined drumy part 16", the end flanges 51 and 52, the brake 49 Vand the shaft 33 wit-h its bearings 31 and 32 as before. .There are also the friction surfaces composed,y of the pairy of friction ringsr40, 41 and the-pair of friction rings 42, 43. In this l'case,how'

ing one of the rings 40 or 41 fixed to'the',

drum part 16h, it fixed to a spider 57,. the hub 58 of which is splined to the shaft. In this case the drum part 16b may vbe keyed fast to the shaft.

Yrial No. 537,656.

`To produce the endwise thrust rI cut a ting; up ythese nuts the spider 55 binds the vdrum v.part 16av toward the. drum part 16h so as to produce the requisite pressure between I thel friction surfaces. "That this pressure may be yielding, I prefer to interposefthe coiledy springs 62 between the spider 57 of the Y l l `drum part 16". 'Theselsprings also permit of the'expansion of the partsunder heat and maintain lthe friction pressure substantially Aconstant under variations from heat. However, lthese coiled springs may, if desired, be dispensed ,withand also the spider 62, the

yfrictionring 41 being, under those circumf stances, made fast to thedrum part16b.

. In the engine shownin Figs. 4,-5 and 6 the cranks 63, 64 and crank disks 65, 66 and f eccentrics '67,' 68 aremounted directlyL on thek ,drum "shaft 33, and the additional brake 69 for occasional use is applied to the crank disk 66. vl.The cylinders .70 and 71 arel made of very large bore sufficient to maintain .the requisitef'pull;in hoisting and swinging without the'introduction .of gearing, shafts and bearings.V fThe ybrake 69 upon. the 'crank that `iskeyed` to the shaft while theloos'e drum.16EL is controlled bythe brake V49 actldisk or iy wheel 66, controls the drumy `16b ingv directly upon it. vThe steam reverse l valve-7,2 is of wellv known construction and lis operated by handr lever '73. Leverk 73together with foot-lever 74 for operating brake 49 and foot lever .75 vfor operating brake 69 are larrangedin the most convenient position for the operator.
